An in-line adhesive, useful for transdermal delivery devices comprising a mixture of high and low molecular weighted polyisobutylene having a ratio HMW PIB:LMW PIB in the range of about 5-40:95-60 which is substantially free of plasticizers and tackifiers is disclosed. The adhesive finds particular use as a component of a transdermal delivery device for delivering oily non-polar agents such as nicotine, benztropine, secoverine, dexsecoverine, and arecoline.
